While checking connections on my SL70C, I saw this little white box. What it's purpose?

What do you have on the boat thats a Raymarine ? depth sounder maybe
 
IS this thread like "Let's Make a Deal" and we get to pick what curtain we want? People here will help but you have to give more information including pictures to get a real answer.
 
Simple, it's a widget or maybe a thingamajig.
 
It could be a number of things ,GPS, Fish target, Chart plotter.
 
Its the flux capacitor.

Seriously though it probably is a SeaTalk junction box. Older SeaTalk devices; gps, depth, heading sensor/compass get connected to the junction box and then the box has a single connection to the display.

The boat has a Raymarine Radar, connected to the SL70C. I do have the SmartCraft display also. This "white box" is basically hanging loose, but is behind the SL70C.

It appears to have gotten hot at some point. I am not sure even what it is. What I do know is that I still have the intermittent issue with the GPS Sensor not getting a fix. I still have the old RayStar 120 sensor and was giving one last crack on checking connections before I bought a new one.
 
You may have found it , look on raymarine web site for any info , and maybe call em
 
I was able to track down the install guide. It is the SeaTalk box that has input from the GPS sensor. I have a feeling this is where my problem lies. I am going to take the cover off of the box and see what the connections look like. I WAS able to see that the black wire was either stripped of insulation or maybe even disconnected on one side of the connection. This could certainly be the issue.

I have the exact same factory install as you on my 2004 (I even have the white box). I get the "NO FIX" once in a while, but not often enough to bother me. The workaround for me is to kill the battery switches to cut power to the Raystar120 to clear out its buffers (according to my research I have a 120 that is from a batch that had a fab problem that would generate this buffer overflow problem if power is left on the 120 for a long period of time). Its just a pre-launch check for me. 90% of the time I don't have to do the workaround.

Did the factory wire the NMEA0183 from your SL70CRC to the Smartcraft speedometer on your boat to give you GPS speed, distance to waypoint, fuel to waypoint on the speedometer? Same for the VHF (I suspect you also have the Ray215?) - is the NMEA connected to it to give it lat/long for DSC? They did not on mine - I had to do it myself thanks to some coaching from Henry.

Honestly....I havent played with it that much with regard to distance to waypoint, fuel to waypoint etc. I am really trying to get the basics of it working properly before I attempt to learn all that it is capable of. I need the GPS for night time, not during the day as I am only on a 30K acre lake. I do know that when my GPS is not working, I get some sort of NMEA error on my VHF (Raymarine, not sure of model though).
 
The GPS connections will probably look like this inside:
